The tools and systems areespecially helpful for maintaining a baseball or softball field.

2. Description of Related Art

Since the invention of the game of the baseball and softball there hasbeen a need to create and maintain fields in these sports. The areas ofhome plate and the pitcher's mound are two parts of the field that arein constant need of repair and maintenance, and also most important tothe players of the game. It is essential for the safety and performanceof the ball players that the dirt or clay surrounding the pitchingrubber and home plate be smooth and firm. This type of smooth playingsurface can be achieved by compacting clay with a tamping device.Generally, a tamp is used by repeatedly applying the flat surface of thetamp to loose and uneven dirt or clay to ultimately create a generallyhard, smooth and flat surface. Although tamps can be used for a varietyof materials and surfaces, the most common use is for packing dirt andclay.

As field maintenance for baseball and softball fields has modernized,tamps too have evolved. Originally, tamps were comprised completely ofwood with a flat base and long handle, such as that of a broom stick.Over time, aspects of the tamp, also known as a tamper, have changed toprovide a better tool, however, the overall design has largely remainedto same.

To overcome the deficiency of using wood, steel was used to replace woodat the base of the tamp but still comprised a wooden handle. The use ofa heavier material at the base allowed for the clay to be easily packeddown with less force required by the user.

Tamps were later produced comprising steel, or other metals, throughoutthe entire tool so that both the shaft or handle and the base werecomprised of the same material. This, like the advantage above, allowedthe user to utilize the weight of the tamp to compact the clay versususing a lot of physical strength. An all steel, or all metal, tamp alsoprovided a much sturdier tamp as the base and handle are typicallywelded together. One disadvantage however, is that the tool is extremelyheavy and requires a certain amount of strength to use properly.

To assist the user in lifting and forcing down the tamp, tamps werecreated with perpendicular handles. Handles added allow users to easilylift the tamp and provide an additional means for applying a downwardforce to pack the clay.

Tamps have also been created with adjustable handles, allowing the userto pack dirt or clay from different angles. For example, US ApplicationPublication No. 2005/0025580 entitled “Tamper with Pivoting Handle,”which is incorporated herein by reference in its entirety, describes atamp, or tamper, in which the handle pivots where the handle meets thebase of the tamp. Another example of a tamp with an adjustable handle isU.S. Pat. No. 7,603,780 entitled “Multi-Purpose Tool,” which isincorporated herein by reference in its entirety, which also describes atamp in which the handle pivots where the handle meets the base of thetamp. Although such tamps provide an added feature, since the handle isheld in place so low on the handle, and with little support, such tampshave a tendency to break as the tamp is applied to uneven surfaces dueto the strain on the tamp where the base and handle meet.

Additional tamps provide for a tamp with a removable base. For example,US Application Publication No. 2007/0209532 entitled “Yard WasteTamper,” which is incorporated herein by reference in its entirety,describes a tamp that can be added to the end of a rake to use whentamping leaves or light yard waste. The tamp is held in place by apressure fit. This type of fit however does not secure the tamp wellenough to be applied to harder surfaces such as clay or dirt. Evenfurther, the tamp has a convex face with protrusions to facilitatepacking leaves in a bag, which structure is not preferred for providinga smooth, flat surface to a playing field. Another example of a tampwith a removable base is US Application Publication No. 2003/0235470entitled “Soil Tamper,” which is incorporated herein by reference in itsentirety. This reference describes a tamp with a plate and short hollowsleeve capable of receiving a handle. The handle is inserted into thehollow sleeve and secured by a pin. Due to the low height of the hollowsleeve, only a small portion of the handle is secured. This type ofattachment is not very sturdy and over time is susceptible to breakingwhere the handle meets the hollow sleeve.

Earlier efforts to improve tamps are described in U.S. Pat. Nos.2,234,831 and 3,739,562. Despite attempts to make a stronger, moreefficient and easier to use tamp, the prior art has failed to provide atamp with such characteristics. There is still a need for a tamp that iseasy to use, well supported where the handle and base meet, thatprovides an optionally removable handle, and is strong enough to lastthe wear and tear of constantly pounding the tool on uneven clay anddirt.

Other tools used for maintaining baseball and softball fields are known,such as hoes and rakes. Common hoes include push & pull hoes, scufflehoes, loop-hoe edgers, and stirrup hoes. The loop-hoe edger and stirruphoes, for example, are tools with an elongated handle and tool head inthe shape of a loop, usually a trapezoidal loop. The edges of the loopare relatively sharp, making the tool ideal for edging. In theapplication of baseball and softball field maintenance, loop-hoe edgesare used to define the boundary between a granular surface and a grassyarea. During use, the tool is positioned such that the loop isperpendicular to the ground surface. The user then performs the edgingprocess by dragging or pushing the loop through the granular surface andalong the edge of the grassy area. This action moves, spreads, orotherwise redistributes the granular material and cuts into the edge ofthe grassy area to shape the grassy area into a desired shape.Similarly, rakes are used to re-distribute the dirt or clay on a playingfield and to remove unwanted debris from the field. Since these arecommon tools for baseball and softball field maintenance, it would bedesirable to have a tool system comprising interchangeable tool heads,which tool can be converted from a rake to a hoe, then back again.

One known structure of a hoe head is disclosed in U.S. Pat. No.8,079,423 entitled “Cultivating Tool,” which disclosure is herebyincorporated by reference herein in its entirety. The patent discloses atool with a concave shape and narrow scraping blade. Another hoe isdescribed in U.S. Pat. No. 6,152,241 entitled “Dual Blade Hoe,” whichdisclosure is hereby incorporated by reference herein in its entirety.This patent discloses a tool with two independent blades joined by acurved support.

What is still desired for scuffle hoes for maintaining baseball andsoftball fields is a more durable tool with multiple scraping blades.Additionally lacking is a system of interchangeable tool heads,especially a tool system comprising a rake and hoe tool head. Thus,there is a need for improved landscaping tools for maintaining baseballand softball fields.

SUMMARY OF THE INVENTION

Embodiments of the present invention relate to systems, tools, andmethods used for cultivation and landscaping, particularly on baseballand softball fields.

Embodiments of the invention provide for an improved tamp, and moreparticularly for a tamp with a plate and shaft, where the height of theshaft is greater than or equal to the length of a side of the plate. Inembodiments, support fins are secured between the plate and shaft. Allof which provides a durable tool with improved characteristics.

One mode of operation responsible for success of the inventive tamp isthat the reinforced tamp plate and shaft, with a shaft height to platelength ratio of 1:1 or greater, provides the capability of withstandingrepeated striking of the tamp on a hard surface without breaking thetool at for example the tool pole. Some tamps provide a tamp plateconnected directly to and perpendicular to the tamp pole with little orno added support, and do not provide an added shaft between where theplate and pole meet. Since this connection is not well supported thisarea becomes vulnerable. Over time these tamps have a tendency to breakwhere the plate joins the pole as the tamp is constantly applied touneven clay and dirt surfaces. Other designs employ a shaft to receivethe pole, however, the height of the shaft relative to the length of theplate sides is too short to address this problem of breakage. In suchdesigns, it is the handle (otherwise referred to as the tool pole ortamp pole) that is susceptible to breaking where the handle meets theshaft. In contrast, the invention's connection between the plate andpole is reinforced with a shaft height greater than the plate width.This configuration provides for a stronger connection between the handleand plate, thereby strengthening the area most likely to break andproviding for a more durable tool. Further, optionally securing theshaft further up the pole and/or optionally reinforcing the plate andshaft with support fins provides a tamp that is extremely durable.

An embodiment of the invention is a tamp comprising: a steel plate withan upper surface and a lower flat planar tamp face; a hollow shaft, forreceiving a handle, disposed on and fixed perpendicular to the uppersurface of the steel plate; and multiple support fins disposed on andextending from the upper surface of the steel plate to the hollow shaft,wherein an edge of each fin is disposed relative to the shaft at anangle of 45 degrees or less. In embodiments, the steel plate and shaftcan be of unitary, single-piece construction (e.g., molded).

Such tamps can comprise a lower flat planar tamp face having sides ofequal length forming a square outline and a shaft height greater thanthe length of the tamp face sides. In embodiments, the ratio of theheight of the hollow shaft to the length of the tamp face side(s) may bein the range of 0.5:1 to 4:1, such as for example 1.2:1 to 2.3:1. Inspecific embodiments, the ratio of the height of the hollow shaft to thelength of the tamp face sides is about 1.1:1, or 1.2:1, or 1.3:1, or1.4:1, or 1.5:1, or 1.6:1, or 1.7:1, or 1.8:1, or 1.9: 1, or 2:1. Forexample, in one specific embodiment, the tamp may have a shaft with aheight of 11 inches and tamp face sides with a length of 8 inches, whichprovides a height-to-side ratio of about 1.4:1.

In embodiments, the tamp can have a handle of wood disposed in theshaft, which handle is removable. A portion of the handle and the hollowshaft can be configured with a square cross section and sizedappropriately such that the handle is received in the hollow shaft in aslip fit or pressure fit manner. When the handle is disposed in theshaft, it can fit in a manner where there is some or no movement betweenthe shaft and handle. Other materials, such as adhesives and/or screwsmay or may not alternatively or in addition be used to secure the polewithin the hollow shaft.

Support fins can be added for additional support between the handle andthe tamp plate. Embodiments with no support fins are also possible. Theshape and size of the support fins is not critical and any structurethat provides added support between the handle and tamp plate can beused, including for example crescent-shaped fins, rectangular bars orplates, triangular plates, and/or cylindrical bars. In embodiments, eachfin can be substantially triangular and have two sides disposedrespectively along the upper surface of the plate and the outer surfaceof the shaft. In this manner the fins can further prevent bendingbetween the shaft and plate and/or between the pole and plate. The finscan also have a semi-circular cut out in a side of the fin to providesome flexibility and allow for a small amount of bending between theplate and shaft during use.

Another embodiment of the invention is a tamp comprising: a metallicplate with a first surface and a second surface disposed parallel to thefirst surface, wherein the second surface is configured such that thesecond surface can be used to compact particulate material into a morecompressed state when the second surface is pounded against theparticulate material; and an open columnar member, for receiving ahandle, disposed on and fixed to the first surface of the metallicplate; wherein the metallic plate has sides of equal length forming asquare outline and the open columnar member has a height that is greaterthan the length of the metallic plate sides.

Such tamps may have a planar second surface and may further comprisemultiple support members disposed on and extending from the firstsurface of the metallic plate to the open columnar member. All or aportion of the second surface may comprise indentations and/orprojections of any shape or size, such as semi-spherical, pyramidal,and/or box-like. In embodiments, the multiple support members are fins.The fins may be disposed on and extend from the first surface of themetallic plate to the open columnar member, wherein an edge of each finis disposed relative to the shaft at an angle. In embodiments, each finis substantially triangular, and an edge of each fin forming thehypotenuse of a right triangle may be disposed relative to the shaft atan angle of 45 degrees or less, such as 40 degrees, or 35 degrees, or 30degrees, or 25 degrees, or 20 degrees, or 15 degrees, or 10 degrees, or5 degrees, or any range in between any of these endpoints. Each fin mayhave a semi-circular cut out in a side of the fin.

Methods of using tamps are also included within the scope of theinvention. Such methods can include using any of the tamp configurationsdescribed in this specification. For example, one such method cancomprise using a tamp comprising: a steel plate with an upper surfaceand a lower flat planar tamp face; a hollow shaft, for receiving ahandle, disposed on and fixed perpendicular to the upper surface of thesteel plate; and multiple support fins disposed on and extending fromthe upper surface of the steel plate to the hollow shaft, wherein anedge of each fin is disposed relative to the shaft at an angle of 45degrees or less, wherein the use comprises repeatedly pressing the lowerflat planar tamp face against a ground surface to compact the soil witha downward force.

DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS OF THE INVENTION

Reference will now be made in detail to various exemplary embodiments ofthe invention. It is to be understood that the following discussion ofexemplary embodiments is not intended as a limitation on the invention.Rather, the following discussion is provided to give the reader a moredetailed understanding of certain aspects and features of the invention.

In accordance with embodiments of the present invention, provided is atamp comprising a shaft perpendicularly connected to a base plate, wherethe shaft and plate are further secured together by fins disposed alongsubstantially the entire length of the plate and/or the height of theshaft. The height of the shaft can be greater than or equal to thelength of one side of the plate. Further, the tamp can be connected to apole or handle to provide leverage to a user when using the tamp. Suchtamps provide a durable construction with improved performancecharacteristics over that of existing designs.

FIGS. 1-5 illustrate an embodiment of the inventive tamps, while FIGS. 6and 7 illustrate embodiments of individual tamp components. As shown, atamp 20 is provided which comprises: a steel plate 26 with an uppersurface 26A and a lower flat planar tamp face 26B (shown in FIG. 7); anopen columnar member 24, for receiving a handle 28, disposed on andfixed perpendicular to the upper surface of the steel plate; andmultiple support members 22 disposed on and extending from the uppersurface of the steel plate to the hollow shaft, wherein an edge 25 ofeach fin 22 is disposed relative to the shaft 24 at an angle of 45degrees or less.

More specifically, the illustrated tamp 20 comprises a square metal baseplate 26, a metal shaft 24, 4 metal fins 22 (3 are shown) welded to theplate 26 and shaft 24, and a wooden handle 28 inserted into the hollowshaft 24. In preferred embodiments, the metal is steel. The tamp 20 canbe cast or one or more of the individual components welded together. Oneside of the base plate 26, otherwise referred to as the lower flatplanar tamp face (shown as 26B in FIG. 7), is configured such that theplate can be repeatedly pounded against a surface such as the ground tocompact the particulate material into a more compressed state. This tampplate 26, also referred to as a plate, base plate or base of the tamp,is the part of the tool which comes in contact with the dirt or clay.This flat substantially planar surface of the plate, when forcefullyapplied to the ground by a user, creates a flat, smooth clay or dirtsurface by compacting particulate material into a compressed state. Itis preferred that this lower surface of the tamp plate is smooth anddoes not comprise protrusions. If used for another purpose, suchprotrusions may prove useful and can be included.

For ball fields, such as baseball and softball fields, it is preferredfor the clay or dirt to be packed tightly so that the clay or dirt willremain flat and in place for an extended period of time. In order toefficiently pack down clay or dirt it is desirable to have a tamp 20with a plate 26 large enough to cover a great amount of area, yet smallenough that the tamp 20 is easy to operate. The greater the size of thetamp 20, the greater the weight of the tool. According to embodiments ofthe invention, the face plate 26 can be a planar sheet of metal withdimensions ranging in size from about 1 inch to 18 inches for the lengthof one or more side. For example, a plate 26 of the tamp 20 can besquare and measure 2×2, 3×3, 4×4, 5×5, 6×6, 7×7, 8×8, 9×9, 10×10, 11×11,or 12×12 inches square, with preferred embodiments being an 8 inch by 8inch square metal plate. Rectangular plates 26 are also possible, withmeasurements for example ranging from 1-18 inches for one or more of thesides, such as a 2×8, or a 3×9, or a 4×10 inch rectangular plate.Additionally the thickness, or height, of the plate 26 can range fromabout 0.1 inches to 5 inches, including 0.5 inches, ¼ inch, ¾ inch, 1inch, 1.5 inches, 2 inches, 2.5 inches, 3 inches, 3.5 inches, 4 inches,or 4.5 inches, or any thickness in between, with preferred embodimentscomprising a plate thickness of 0.5 inches or 0.25 inches. Whilepreferred embodiments of the invention comprise a plate 26 made ofmetal, particularly ferrous alloys such as steel, plate 26 can also bemade from plastic, wood, aluminum alloys (e.g. Alnico, Duralumin),copper or copper alloys (e.g. brass, bronze), nickel alloys (e.g.Alumel, Chromel), platinum, titanium or any other metal or alloy.Further, though in preferred embodiments the plate shape is square, thetamp plate 26 may also be rectangular, circular, triangular, pentagonal,hexagonal, heptagonal, octagonal, star shaped, or have any irregularpolygon shape, whether convex or concave.

FIG. 2 also illustrates that, in embodiments, the height 24L of theshaft 24 can be greater than the length 26L of a side 26S of the plate26, providing a height to length ratio greater than 1:1. For example,for a tamp 20 with an 8×8 plate and an 11 inch shaft, the height towidth ratio would be about 1.4:1. The ratio of the shaft height to plateside length can for example be 1.2:1, 1.3:1, 1.4:1, 1.5:1, 1.6:1, 1.7:1,1.8:1, 1.9:1, 2:1, 2.1:1, 2.2:1, 2.3:1, and so on.

Also shown in the figures is that the angle between the shaft 24 and theoutside edge 25 of the fin 22 can measure between 0-90 degrees, such asless than 45 degrees. Additionally, the angle of the fin 22 between theedge of the shaft 24 and the outside edge 25 of the fin 22 can be anyangle between 0 and 90 degrees, with preferred embodiments having anangle less 45 degrees. Embodiments can include fins 22 with an edge 25disposed at any angle to the shaft, including for example from 0-90degrees, such as from 5-85 degrees, 10-75 degrees, 15-65 degrees, 20-55degrees, 25-50 degrees, 30-40 degrees, 35-60 degrees, 45-70 degrees, or35-45 degrees, or any range or value in between any of these statedvalues. In embodiments, the number of fins 22 may correspond to thenumber of corners or sides on the base plate 26, and the size of thefins 22 may correspond to the size of the base plate 26 and shaft 24.The number of fins 22 can be 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12and so on. Fin placement may be along the diagonal between the shaft 24and a corner of the plate 26 and/or perpendicular between the shaft 24and a side of the plate 26 and/or somewhere between. Fin placement mayalso be random, so long as the fin 22 provides support and is connectedto both the plate 26 and the shaft 24. The fins are preferably providedon the tamp in a manner that increases the distance of the handle fromthe moment of impact to decrease the amount of stress experienced by thetool during use, especially at the transition point between the handleand tamp plate. In embodiments each fin 22 may also comprise asemi-circular cut out 23 on one side of the fin 22 in order to aid inabsorbing the impact felt by the user and the tool 20 as the tool 20hits the ground. The cut out 23 provides for flexibility between theplate 26 and the shaft 24 by allowing the fin 22 to bend when the toolimpacts the ground with an amount of force. The cut out 23 can also beany shape, including but not limited to, a triangle, a square, apentagon, a circle, a star shape or any irregular shape. The cut outneed not be “cut” out of the material, rather the fin can be molded orformed in any such desired configuration providing for a passagewaybetween the fin and shaft when joined thereto. In preferred embodimentscut out 23 is located in the range of about 0.5-2 inches, such as 0.7665inches, from the base of the tamp 20, however the cut out 23 may beplaced anywhere on the fin 22. Additionally, in preferred embodimentsthe fins 22 are made of the same material as the shaft 24 and plate 26,however all or some of the parts of the tamp 20 may optionally becomprised of the same or different materials. For example, fins 22 canbe made of metal, wood, plastic, or any combination thereof.

According to embodiments of the invention, the fins 22 may be secured tothe plate 26 and shaft 24 by means suitable for the material the partsare comprised of. In some embodiments, the tamp shaft 24 and tamp plate26 can be joined together through a means for fastening. The means forfastening can include welding, glue, adhesive, one or more screws, oneor more nails, or pins, or any combination thereof to hold the piecestogether. Additionally or alternatively, the fins 22 may fasten to theplate 26 and shaft 24, particularly by a hinge, or latch fastener or byinterference fit. The fins 22 may also be removable by inserting thefins 22 into a track disposed on the shaft and/or plate into which thefins 22 can be inserted by sliding engagement. Moreover, embodiments ofthe invention can include a plate 26, shaft 24, and fins 22 formed as asingle part construction of one material. The fins 22 of the inventionprovide added strength to the inventive tamp 20 creating a tamp that isextremely durable and built to withstand the wear over time.

In embodiments, the tamp plate 26 is connected perpendicularly to oneend of the tamp shaft 24 in order that the pole or handle 26 may bejoined with the plate 26 through the opposite end of the shaft 24. Inpreferred embodiments, the base of the hollow square tamp shaft 24 iscentrally secured to the plate 26, leaving the other end of the shaft 24for receiving the tamp pole or handle 28. The plate 26 may be, inembodiments, 6 inches×6 inches, 7 inches×7 inches, 8 inches×8 inches, 9inches×9 inches, 10 inches×10 inches, 11 inches×11 inches, 12 inches×12inches, or more.

The pole 28 may be any rodshaped material extending from the plate 26 of the tamp 20 to areasonable height for the user. In preferred embodiments the tamp pole28 is circular wooden rod, resembling a broom stick, with a squareshaped end, or an end that complements the cross sectional shape of theinterior of the shaft, such as a round or triangular end. The squaredend of the rod 28 is inserted into the shaft 24 of the tamp 20 andprovides a fit to minimize movement between the pole 28 and shaft 24.The circular part of the pole 28 provides for a comfort grip.Embodiments may include attachment of other tools at the end of the tamppole 28 opposite the base 26 of the tamp 20, or embodiments where thepole 28 terminates at an end that has no additional attachment attachedto the pole 28.

In embodiments, the base of the pole 28 comprises two holes drilledpartially or completely through the pole 28 to align with the holes 24Hor voids of the tamp shaft 24. In preferred embodiments the holes arelocated 2.75 inches from the bottom of the pole 28 but can be placed atany location so long as the holes in the handle align with the holes inshaft. In embodiments, the pole 28 may also comprise more or less thantwo holes and can range for example from 0-5 holes, such as 1, 2, 3, 4,or 5 holes or voids. The holes or voids in the pole 28 provide a meansof securing the pole within the shaft 24 of the tamp 20. It is importantthat the two pieces are held together well as they will have towithstand the forces of lifting the base 26 of the tamp 20 and strikingit on the ground. Embodiments of the inventive tamp handle 28 may besecured together by a variety of means such as welding, gluing,screwing, nailing, or bolting, or any combination thereof with preferredembodiments using pins to secure the handle 28 in place within the shaft24. In preferred embodiments the handle 28 is easily removable and notpermanently fixed to the rest of the tamp 20, so as to provide for easyreplacement if required.

Inpreferred embodiments the shaft 24 of the tamp 20 is 2 inches by inchesand measures 11 inches in height. Going through the shaft 24 are twosets of circular holes 24H on opposite sides of the shaft located about2.75 inches and 7.5 inches from the base of the shaft. The base plate 26of the tamp is 8 inches by 8 inches and measures 0.5 inches in height.The fins 22 of the shaft correspond to the height of shaft, and lengthof the plate to form a right triangle measuring 11 inches by 4.3192inches; where the angle of the fin 22 at the top of the shaft 24,between the edge of the shaft 24 and the outside edge of the fin 22measures 21.534 degrees. A semi-circle 23 is disposed on side 22B of thefin. The bottom edge of the semi-circle 23 is disposed 0.7665 inchesfrom the bottom of the fin and the top of semi-circle 23 is disposed8.0165 inches from the top of the fin.

Embodiments of the invention also provide a tool system comprising ahandle, a first and second support bar or bracket, a rake attachment,and/or a hoe attachment. Preferably, the system comprises means forattaching the tool heads to the handle in a releaseable manner.

Each component can be made of any material, such as wood, plastic, ormetal. The interchangeable handle 38, shown as the embodiment in FIGS.1-5, is preferably made of wood or composites. The shape of the handleis not critical, however, in embodiments the handle 38 comprises aportion having planar surfaces to allow for secure attachment of thesupport bars 32 to the surface of the tool handle 38. In embodiments,provided is a handle 38 comprising a polygonal shaped base, a polygonalor cylindrical shaped main body, and a cube or hemispherical shaped tip.The handle 38 can be cylindrical or a combination of cylindrical andpolygonal.

The handle 38 can be molded, carved, or shaped from individualcomponents and attached together to form the handle, or the handle cancomprise a single, seamless piece of material which is molded, carved,or shaped to reflect one or more distinct sections. In one embodiment, abase with a square cross section (e.g., polygonal base) providesadditional reinforcement when the interchangeable handle is in operablecommunication with an attachment by preventing rotational motion of thehandle when placed between a first and second support bracket or supportbar.

The base of the handle 38 can comprise one or more void, such as twovoids, traversing the enclosed volume of the square base and causing twoholes in the surface in each of two parallel sides of the square basesection. These voids and corresponding holes can be any diameter toaccommodate a desired sized screw, bolt, peg or other securing means forsecuring the support bars to the handle. In embodiments, the holes areabout 0.3750 inches in diameter, such as 0.1 to 0.5 inches, and arecapable of receiving a fastening device such as a screw, a peg, bolt, orpin. The fastening device serves to operably connect the interchangeablehandle to a tool attachment. The cylindrical main body and hemisphericaltip sections of the handle provide a comfortable area for the user tograsp and operate the handle.

The first and second support brackets 32, shown together as theembodiments depicted in FIGS. 1-5 and individually in FIGS. 8-13, arepreferably made of metal and each provide a main section 32A, an angledsection 32B, and an interface section 32C. In embodiments, the supportbars 32 (as shown in the figures) can comprise a planar bar that isshaped (e.g., bent) to provide a first leg 32A disposed perpendicular toa second leg 32C. The support bar 32 can be a single piece or can beformed from multiple components for example welded or attached togetherto form the support bracket. Depending on the material, the support bar32 can be molded, forged, carved, or shaped to reflect the distinctsections.

Each support bar 32 has a length between 5 and 24 inches, such asbetween 14 and 18 inches along the long axis of the bracket. The supportbar 32 can have a width of between half an inch to 3 inches, such asbetween 1-2 inches. The support bar 32 can have a thickness ranging fromabout 0.1 to 1 inch, with thicker and/or wider brackets being stronger.

In one embodiment, the main section 32A (e.g., first leg of the supportbar) has a length of 10 inches, such as from 4-18 inches, and comprisesa rectangular planar surface with two holes 32H for receiving afastener. Each hole 32H is approximately 0.375 inches in diameter, suchas from 0.1-0.5 inches, and is centrally disposed between the parallel10 inch sides of the surface, approximately 0.75 inches away from eachof these parallel sides, such as 0.2-1.5 inches, or a correspondingdistance depending on the overall length of the tool head. The first leg32A of the support bar 32 is attached to a side of the handle 38 and theplanar surface of the support bar 32 contacts or interfaces with a sideof the handle 38. The interface section 32C of each support bracket(e.g., second leg) is disposed perpendicular to the main section 32A,and can be attached to the main section 32A through the angled section32B. The first leg 32A, second leg 32C, and transitional portion 32Bbetween the first 32A and second leg 32C can be disposed such that whentwo support bars are used, the two combine to provide a generallyY-shaped support for attaching the handle to the tool heads. Theinterface section 32C, or second leg, has a minimum length of 1 inch,such as from about 1-4 inches, and comprises a rectangular planarsurface with one hole for receiving a fastener. In embodiments,depending on the overall size of the tool, the length of this leg 32Ccan be shorter than one inch, such as about 0.1-1 inch. In oneembodiment, the hole is approximately 0.375 inches in diameter, and iscentrally disposed between the parallel 1 inch sides of the surface,approximately 0.75 inches away from each of these parallel sides. Theangled section 32B of each support bracket 32 connects or provides thetransition between the two previously described sections forming a firstangle between 15 and 30 degrees with the main section, such as fromabout 5-45 degrees, and a second angle between 105 and 120 degrees withthe interface section, such as about 90 to 145 degrees. In oneembodiment, the first angle is approximately 21 degrees while the secondangle is approximately 111 degrees. The angled section 32B has a lengthbetween 3 and 7 inches, and comprises a rectangular planar surface withno holes or voids. The second leg 32C of the support bars is attached tothe tool head.

The rake attachment 45, an embodiment of which is shown in FIGS. 1-5,10, and 11 is preferably made of metal or polycarbonate and provides arake head 46 and a rake head brace 44 (e.g., support bracket). The rakehead 46 has a width between 30 and 40 inches, such as 10 to 45 inches, auniform thickness between 0.5 and 1.5 inches, and comprises an array ofteeth 47 or tines, and one or more holes 46H for receiving a fastener.In one embodiment, the rake head 46 has 4 holes 46H for receiving afastener, and a width of 36 inches, but any width and number of holesand fasteners can be used. The fasteners can be used for attaching thesupport bracket 32 to the backside of the rake 40 and/or for attachingthe second leg 32C of the support bars 32 to the rake head 46. The arrayof teeth 47 is formed by an alternating distribution of voids and teeth.Each tooth 47 comprises a contact section and a distributed section. Thecontact section is directly in contact with a ground surface duringoperation, and can comprise a rectangular column height between 1.5 and2 inches and a width between 0.1 and 0.5 inches. In one embodimentcolumn height is 1.6415 inches, and column width is 0.375 inches. Thedistributed section is approximately 0.8585 inches tall and links eachcontact section to the main rake head 46 to form the array of teeth 47.In embodiments, the teeth 47 can be formed according to conventionalrakes. The sections of each tooth 47 are formed as a result ofalternating voids in the array of teeth. Each void comprises arectangular column volumetrically equivalent to that of the tooth, and atop section. The top section forms preferably a parabolic or triangularshape with the main rake head, causing a corresponding distributedsection disposed between two voids, for each tooth. Two of the fourholes 46H for receiving a fastener are each disposed 2.75 inches fromthe width midpoint of the rake head structure, on either side of themidpoint. Each of these two holes is approximately 0.375 inches indiameter. The other two holes for receiving a fastener, each with adiameter of 0.25 inches, are each disposed 8 inches, or a proportionatedistance depending on the tool, from the width midpoint of the rakehead, on either side of the midpoint.

The rake head brace 44, or support bracket for the back of the rake 40,an embodiment of which is shown in FIGS. 1, 2, 4, 10 and 11, serves tofacilitate a more secure connection between the first and second supportbrackets 32 and the rake head 46. The rake head brace 44 has a widthbetween 15 and 20 inches, a height between 1 and 3 inches and a uniformthickness between 0.3 and 2 inches, and comprises a rectangular planarsurface 44A, a depressed channel 44C on one side of the surface, andfour holes 44H for receiving a fastener. It is not necessary that thedepressed surface be present, however, this will provide for greatersupport for the support bracket 32 placed within the channel. The planarsurface comprises two parallel raised edges 44B, along the long axis ofthe brace, on one side of the surface. These edges are perpendicular tothe planar surface, and form a depressed channel 44C between the edgeson that side of the planar surface. In one embodiment, the rake headbrace 44 has a width of 18 inches. The channel 44C has dimensions of 18inches by approximately 1.5 inches. Two of the four holes 44H forreceiving a fastener are each disposed 2.75 inches from the widthmidpoint of the rake head brace 44, on either side of the midpoint. Eachthese two holes 44H is approximately 0.375 inches in diameter. The othertwo holes 44H for receiving a fastener, each with a diameter of 0.25inches, are each disposed 8 inches from the width midpoint of the rakehead brace 44, on either side of the midpoint.

The support bracket 44 for the backside of the rake head 46 preferablycomprises a C-shaped channel 44C for receiving a leg of the support bars32 that are attached to handle 38. Such a configuration provides threesurfaces for interacting or engaging with a leg 32C of the support bars32, since the support bars are planar. For example, three of the foursurfaces of the legs 32C of the support bars 32 are disposed within theC-shaped channel 44C. When attached to the rake head 46 within thechannel 44C, the three surfaces of the support bars 32 will interfacewith three sides of the channel 44C to provide for a secure handleduring use.

The rake tool 40, an embodiment of which is shown in FIGS. 1-5, may beconfigured by following a sequence including but not limited to thefollowing steps. When operably configured, the entire non-channel sideof the rake head brace 44 is firmly adjacent to the rake head 46. Thetwo components are arranged such that the midpoint of each component arethe same, and the 0.25 inch diameter holes 46H, 44H on each side of therake head 46 and rake head brace 44 midpoints are aligned. Fasteners arethen used in each pair of aligned holes to secure the rake head brace 44to the rake head 46. The 0.375 inch diameter holes on each componentshould also form two aligned pairs, and each of these pairs is thenaligned with the corresponding hole on a support bracket interfacesection. Fasteners are then used in each pair of the aligned holes tosecure the channel side of the rake head brace 44 to the first andsecond support brackets 32. The support brackets 32 are then attached tothe appropriate opposing sides of the interchangeable handle 38 byaligning the 0.375 inch holes 32H on each support bracket 32 with thecorresponding holes on the handle 28. A fastener is used to in each ofthe two trios of two opposed support bracket holes and one traversalvoid.

The C-shaped channel 44C offers additional strength to the componentjunctions by restricting the rotational motion of the first and secondsupport brackets 32 when received by the channel. The channel depth isapproximately the same thickness as the support bracket 32, and thechannel height is roughly the same as the support bracket width. Whenfastening each support bracket to the rake head 46 and rake head brace44 through the 0.375 inch holes, the external rotational force appliedto the fastener (in the case of a bolt or screw) would then yield agreater torque on the components because the applied force would not belost to the rotational motion of the other components. An increase intorque would then lead to a more rigid connection and a faster assemblyor disassembly time and less required applied force. A more rigidconnection allows the tool to operate more effectively for a longerperiod of time because the junction will not loosen, and willconsistently transfer all force applied by the operator to the contactsection of the rake.

The rake head can comprise an elongated tool head 46 with a plurality oftines 47 and a support bracket 44 with a C-shaped track 44C fixed to oneside of the tool head, wherein the second legs 32C of the support bars32 are operably configured such that when disposed in the C-shaped track44C the second legs 32C of the support bars 32 are supported by threesurfaces of the C-shaped track 44C.

The hoe attachment 34, embodiments of which are shown in FIGS. 1-5, and8 and 9 is initially in an unmolded form and comprises two holes 34H forreceiving a fastener, two parallel diverging edges, and a flat,preferably metal, planar surface as shown in FIGS. 8 and 9. In oneembodiment, the attachment has a width of 6.5 inches, a height of 4.5inches, and an approximate thickness between 0.5 and 1.5 inches, in itsunmolded form. The two holes 34H for receiving a fastener are disposedon the lower half of the surface, each 0.5625 inches from the left andright sides respectively, and both 1.25 inches above the lower boundaryof the surface. Each hole is 0.25 inches in diameter. In its moldedform, the attachment 34 has the same width as in the unmolded form, butnow has a height of 2.7434 inches, and a curvature depth of 1.1937inches as shown in FIGS. 8 and 9. The molded form does not change therelative position of the two holes 34H for receiving a fastener. Theparallel diverging edges represent the upper and lower boundaries andare specifically shown in FIGS. 8 and 9.

In embodiments, the scuffle hoe 30 comprises an elongated tool head 34having a hollow semi-cylindrical shape, and wherein the tool head 34 hasan outer surface and an inner surface and each surface is curved betweenany two points on the outer surface or any two points on the innersurface, and wherein the outer and inner surfaces intersect to provide ablade tip for each blade. Scuffle hoes according to the invention cancomprise multiple scraping blades as shown, where one blade is used forcutting and the other blade is used for smoothing.

The hoe tool 30, an embodiment of which is shown in FIGS. 1-5, may beconfigured by a sequence including but not limited to the followingsteps. When operably configured, the hoe attachment 34 is attached tothe interchangeable handle 38 using a first and second support bracket32. The hole 32H of the interface 32C section of each support bracket 32is aligned with the corresponding hole 34H on the hoe attachment 34.Fasteners are then used in a first and second pair of the aligned holes32H, 34H to secure the support bracket 32 to the hoe attachment 34. Thesupport brackets 32 are then attached to the appropriate opposing sidesof the interchangeable handle 38 by aligning the 0.375 inch holes 32H oneach support bracket 32 with the corresponding holes on the handle 38. Afastener is used in each of the two trios of two opposed support bracketholes and one traversal void.
